GE Dishwasher GSD4020Z07BB is leaking water and doesn't drain

When you replaced the pump I am assuming you replaced the whole assembly that pumps water for the wash and drain. See item 310 in this diagram.

If the dishwasher goes through the wash cycle then it was unlikely the thing that was faulty. The pump is shared by both the wash and drain cycle. It is likely the impeller (item 429) is not getting the pulse to change direction so that it draws water from the drain sump to the drain hose rather then to the wash arms as it does in wash cycle. The solenoid connection might be faulty or the controller output is not there.

Check the drain located in the bottom of the dishwasher by removing the tray. It may be a clog. If there is no clog you can remove the drain hose from under the sink, get a bucket hold the hose in the bucket and try to drain it into the bucket. If it drains in the bucket the clog is in the sink drain, if not it can be a clog in the hose. If none of that works it could be the pump on the dishwasher. Good luck.

Hi


Thanks for using FixYa. If you have nuisance water leaks around the base of your dishwasher, you may be using a detergent that is causing too much suds. Cut back on the amount of detergent you use, and see if that makes a difference.

Water that spills through the door vent is usually caused by improperly loading dishes. Leaks from the door itself may be caused by a faulty door gasket or door tightness adjustment. you should check the main tub seal, the door latch, the door gasket, the water-inlet valve, and the fill and drain hoses.

Also make sure the dishwasher is sitting level (you can adjust the front feet up or down, and many units have some type of levelers at the rear).

Water under the dishwasher may be originating from a leaky hose or loose hose connection. Remove the lower front panel, and check the hoses.

An older dishwasher may corrode at the bottom, but this is fairly uncommon. If this is the case with your dishwasher, it's time for a new one.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Hello there
Here is several ideas that will help you
also (fyi) type in search engine how things work and once it opens just enter dishwasher and it will bring you to the dishwasher section ok?
here it is
Dishwasher is leaking water

• Inspect the seals for the main tub, float, heating element and blower diffuser
• Check for overfilling
• Inspect the water and drain hoses
• Inspect the door gaskets
• Check the water inlet valve
• Check the pump

Water or soap leaks around the door

• Make certain that your detergent is intended for dishwashers. Do not use liquid dish soap.
• Inspect the door seal gasket
• Check the door latch
• Inspect the door hinges
• Inspect the spray arms for damage

Water drains through the air gap into the sink

• Check the air gap

If your dishwasher leaks, check these:Main tub seal
Door gasket or seal
Water-inlet valve
Hoses

Main tub seal
Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

1. Lower rack
2. Spray arm
3. Spray arm support
4. Wash/drain impellers


Then pry the seal out of its housing and replace it.


Door gasket or seal
Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak. 


Water-inlet valve
The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses
Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

The water at the bottom is normal if you open it during the cycle. Leak means you need to replace the L-shaped black, molded gasket that is in the lower left or right of your door opening. Replacement is easy - requires no tools. Part can be purchased for about $10 each at Sears parts department.

This has happened to us a few times. There is a gasket inside the door for a solenoid that operates the flap that opens to let dishwasher detergent out. The gasket went bad and water leaked through.

The only thing to do is replace the gasket. It's a $8 part. (A lot for a 1 inch square gasket!) They seem to last about 2-3 years.
